The ocean is not only the cradle of life, but also the treasure house of resources! Do you know how the ocean affects the weather?

Small temperature changes in the ocean will have a great impact on the weather. As we all know, there are three states of water on the earth, namely, solid, liquid and gas. These waters are distributed in the mainland and the atmosphere, and together they form the hydrosphere. Because the ocean accounts for more than 765,438+0% of the earth's surface area, it can be said that the ocean is an important part of the earth's hydrosphere, and water in various States can be transformed into each other under certain conditions. The ocean can influence the weather through the ocean air mass and water circulation, when the ocean temperature drops 1? C, the global atmosphere will increase by 60? C.

At the equator, the sea surface temperature in the eastern Pacific is 0.5? When the temperature is above C for more than 6 months, an El Nino event will be formed. When the El Ni? o event occurs, tropical cyclones in the ocean are few in number but strong in intensity, and the probability of drought in northern South America is high, while heavy rainfall in central and southern South America will lead to floods. However, China often has a warm winter, and the rainfall generally presents a pattern of drought in the south and waterlogging in the north.

The ocean has a great influence on the formation and change of climate. Most of the solar radiation reaching the earth falls on the ocean and is absorbed by the ocean. Due to the large mass and specific heat of seawater, a natural energy storage is formed. The huge thermal inertia of the ocean makes the surface temperature of the ocean change much less than that of the land. It plays a role in buffering and regulating the change of atmospheric temperature.

In fact, people have long discovered the relationship between the ocean and climate. Monsoon, typhoon, cold wave and so on are all climate or atmospheric systems closely related to the ocean. For example, China is a typical monsoon country, and the land temperature is lower than the ocean in winter.

There is an inseparable relationship between the ocean, climate and weather, which can be said to affect the whole body. With the rapid development of marine economy, the risk of marine disasters in coastal areas has become increasingly prominent, and the situation of marine disaster prevention and mitigation is also very severe. Therefore, it is very important to strengthen ocean observation and research and enhance the ability of forecasting and early warning.
